Comment 14 for bug 1207927

Just tried your changes, and the revisions 409 and 410 are working pretty well, but 411 and 412 seemed to change nothing at all.
The Return key just doesn't trigger anything when the focus is in the Filter bar (but it works fine if click the desired treeitem and press Return).

If the idea is to use the keyboard, it would be cool to allow the user to navigate through the filtered treeitems using the keyboard arrows too.
